Now have a look at My_Type_get_type() declaration and definition. My_Type_get_type() always return the same GType. So if you write multiple cast, only one call to My_Type_get_type() is really necessary. But gcc is a good servant and does what you ask him : calls My_Type_get_type() whenever you call it. Think about this kind of loop :

I always took for granted that my name -- Benoît -- was 6 chars long. I was wrong.
It's 7, UTF-8 speaking.
It took me some time this afternoon to understand why sizeof "Benoît" == 8 where i would expect 7. So i hexdump'ed my C file and realized that î is encoded as 0xC3AE.
I'm glad that ASCII chars are still encoded on a single byte in UTF-8 so hacks like this one:

char buf[magic]; /* enough to hold "plop" */

are still 0k.
I'll try to be less lazy and always code :

char buf[sizeof "plop"];

WTF is î ?

U+00EE LATIN SMALL LETTER I WITH CIRCUMFLEX
UTF-8 : 0xC3 0xAE

In French, circumflexes '^' on vowels often replace old French 's' :
- hôpital for hospital
- hôtel for hostel (= hotel)
- Benoît for Benoist
- côte for coste (= coast)
- etc
Benoît is the french for Benedict.

I'll soon make a control-based desklets on it.
I'd like to get the C backend used by GNOME battstat applet (supports only ACPI/APM, but i steel haven't been able to contact its maintainer. I think I'll have to provide a full patch to get a chance to get PMU support in ...

LibGTop
I'm working hard on libgtop. Fixed a nasty bug on Linux/Sparc64.
I've been granted access to 5 Solaris (sparcs) machines in a German University, and started to fix Solaris support. I still haven't decided if this will go 2.8.1 or 2.9.0 ...

Today, i've wasted one hour debugging a network app : receive an UDP packet, unpack it and insert data into a PostgreSQL database. Quite simple. The program sending data is written in C.

I was getting a pg error about bad queries. So i added a try...except and a print statement on exception. Everything looked OK, i didn't understand what was wrong. So i opened a psql shell and a python shell, dumped there my query. Ran fine. I was crazy. I spent 15 minutes sending packet and watching my error log ...

A word about IronPython
I've downloaded IronPython 0.6. I've started an interactive shell. I type dir() brrrrrrrrrrrr ... finally got the result. Feels like a bit slow comparing to python. So i'm looking for application where IronPython is faster than every other python application. I'm thinking about JIT..

If you want to retrieve the type, i.e System.Type, of a class, you have to use the typeof operator :

System.Type st = typeof(Stack);

sweet.

But if you want to retrieve the type of an object, you have to use object::GetType().

System.Type st = my_stack.GetType();

This sucks so much ... why typeof can't be applied to an object ? and this ugly method call makes me crazy ... all the C# API is full of these shits, it seems that may be half of the µ$ hackers were not aware of properties. And guess what, object::GetType() is overloaded ... We're so far from python __class__ attribute :

obj.__class__

KISS

This is a very bad design : it would have been too easy to extend the typeof operator and put everything else in System.Reflection ... i really can't understand why they did this. Even if i think C# is a bit better than Java, it just sucks. I hate these languages that are designed in 6 months... i can't understand ...

emacs tip
I was interested in a feature that is present in a lot of IDE. I don't know if this has a name or if there's a patent on it : when you instert a (, [ or {, a ), [ or } is automatically inserted you don't get unbalanced (), [] or {}
